TOOL.

SPECIFICATION forming part of Letters Patent No. 595,791, dated December 21, 1897.

Application filed December Z2, 1896. Serial No. 616,591. (No model.)

To all whom t Wtcty concern,.-

Be it known that I, WILLIAM H. SoLEY, a citizen of the United States, residing at Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in Tools, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to that class of tools which are operated by steam and air or some analogous motive fluid, and has for its object the construction of a tool of this class which will be simple in construction and certain in operation; and it specifically consists in certain mode of construction and connection of the parts whereby this result is obtained.

In the drawings, Figure l is a transverse section of a tool, showing the working parts in their lowest position. Fig. 2 is a similar view showing the working parts in their upward position. Fig. 8 is a section on the line 3 3, Fig. l, looking to the right. Fig. 4 is a section on the line 4: 4, Fig. l. Fig. 5 is a section on the line 5 5 of Fig. l.

A represents the casing, having secured to it at one end the tool-holder B, having the hollow portion B', adapted to receive the shank of a cutting-tool to be operated on.

O is the anvil.

D is the striker by which the blow is given to the anvil O and by it transmitted to the shank of the tool held in the socket B'.

E is the inlet-orifice to receive the motive fluid from the source of supply.

The upper portion D of the striker D is made of less Width and the shoulder D2 istof greater area than the shoulder D3 of the main portion D of the striker. The portion D ofthe striker slides in a channel F. The upper end of this channel is in communication with the air by port f. Through the portion D and the striker D is cut the passage CZ, the upper end of which is closed by means of the plug d. The portion D of the striker D is provided with orifices d3, leading from the eX- terior of said portion D', and the passage d. The portion G of the striker-chamber above the main portion D of the striker is constantly in communication with the motive fluid chamber with the atmosphere, and are used v for the purpose of exhausting the air in the chamber G. The ports f prevent any back pressure on the top vportion D of the striker in its reciprocation.

I have operated a tool constructed in accordance with the above description and attached drawings and have found the same effective. One of its great advantages is its eXtreme simplicity, there being but one movable part which is self-controlling. v-

Having now fully described my invention, what I claim, and desire to protect by Letters Patent, isy l. A tool'consisting essentially of a case having a chamber, a passage leading to one end of said chamber adapted to convey the pressure-supply, a port through said case, a striker the body ot which at opposite ends is of different areas, and the end of less area being provided with a contracted stem portion having a port, the end of less area and the contracted portion of the striker being in that portion of the chamber communicating with the pressure-supply, a passage in said striker, leading from said port, opening into the end of the chamber opposite to the pressure-supply, and a contracted portion of the casingin which the stem moves and is adapted in its reciprocations to cover the port.

2. A tool consisting essentially'of a case having a chamber, a passage leading to one end of said chamber adapted to convey the pressure-supply, a port through said case, a striker the body of which at opposite ends is of different areas, and the end of less area being provided with a contracted stem portion having a port, the end of less area and the contracted portion of the striker being in IOO that portion of the chamber communicating with the pressure-supply, a passage in said striker, leading from said port, opening into the end of the chamber opposite to the pressure-supply, and a contracted portion of the casing in which the stem moves and is adapted in its reciprocations to cover the port, there being an exhaust-port beyond the closed end of the contracted portion.

3. A tool consisting of a case, a chamber in 'said ease, a striker in said chamber having 4. A tool 'consisting essentially of a case, a chamber in said case, a striker in said chamber having the body at the striking end of greater area than the opposite end, a contracted stem beyond said last-mentioned end, a port in said stem, a passage through the body of said striker to the striking end connecting with said port, a contracted portion of the case in which said stem moves adapted in the reciprocations of the stem to cover said port, and a passage leading to that portion of the chamber adjacent to the portion of the body of the striker of less area adapted to convey the pressure-supply, and an opening through the case in the striking end of said chamber adapted to be covered and uncov ered in the reciprocations of the striker.

In testimon y of which invention I have hereunto set my hand.

WILLIAM I-I. SOLEY.
